So here's how it goes:
1-Tillerson eliminates 2300 jobs. Claims of 'streamlining'.
2-Surprise, surprise!! It's discovered that the DoS 'can't function efficiently' due to lack of staffing
3-These jobs (probably renamed or re-classified) are filled with Trump favourites & 'spies'
Remember that the DoS handles the vast majority of our foreign contacts and as a result a great number of foreign entities wanting to do business with the US. This 'streamlining' is a great way to stack the odds in favour of pro-Trump deals.
